Recommended: Physics of volcanic eruptions
What would it like to be like to see a volcano erupt that is coming towards you? Well many people would find it terrifying and cool at the same time. There is a big possibility that you would die. Unless you get warned early and try to move out of the state as fast as possible. I would think it would be terrifying 100% because I don’t want to get killed by all the ash, pumice and lava. When a volcano explodes and you see it coming towards your way, you don’t think about how cool it looks. You think that you’re probably gonna die.
Now I’m going to ask the question, “What volcano eruption would you rather be in, Mount St. Helens, or Mount Vesuvius?” I’m sure you know the story of what happened to pompeii, but what about The volcano, Mount St. Helens that wiped out the city below it? Well if you don’t know the story of Mount St. Helens, I’m going to describe and compare what it was like compared to Pompeii.

Mount St.
Helen’s Latest eruption was May, 18 1980. Only 57 people died in the disaster while in Pompeii, more than 2000 people died. The reason why that pompeii had more people die, was because, First of all, they didn’t have the technology to tell them whether the volcano would erupt or not. Secondly, they didn’t know the volcano would erupt, because of earthquakes happening all the time. Finally they didn’t realize they needed to get out until it was too
late. Now I’m moving on to the differences of Mount St. Helen’s eruption. First, they had advanced technology.. Secondly, they had a far more better idea when the volcano was going to erupt. The Pompeians had no idea at all that Mount Vesuvius was going to erupt. Another thing I want to say is, that only 57 people died while everyone else made it out alive. Finally, the 2 volcanos erupted in different times. For the final paragraph I’m going to be talking about their similarities. First off, they’re both famous volcano eruptions. Secondly, they both were preceded by tremors. In addition, they both spewed pumice and ash. Another reason is, that both volcanos wiped out the whole city below them. They both killed lots of people, and finally, they both are very famous and people love to learn about these 2 volcanos.
On the afternoon of 24th August 79 AD, a volcano called Mt. Vesuvius erupted, which resulted in destroyed lives of citizens, it was estimated that there were 10 to 12 thousand people who occupied the city .The cities of Pompeii, Herculaneum and a few others were severely affected by the eruption. The cities are well known for its beautiful landscapes and its temperate climate.Pompeii is based in the south, close to Naples in the region of Campania in Italy.The eruption started a series of events such as pumice,rocks and ashes falling down and caused hot volcanic gases to rise high in the sky, people from around 100 miles away could see the event unfolding.The remains of Pompeii and other cities was frozen in time due to the pyroclastic surges
Helens tallied up to be the most deadly and destructive eruption the United States had ever seen. “Approximately fifty-seven people were killed directly from the blast and 200 houses, 47 bridges, 15 miles (24 km) of railways and 185 miles (298 km) of highway were destroyed; two people were killed indirectly in accidents that resulted from poor visibility, and two more suffered fatal heart attacks from shoveling ash (Wikipedia 3)”. Just when it seemed the nightmare was over a second eruption occurred the following day. A quarter of the lava was fresh, and included ash, pumice, and volcanic bombs, and the rest was older molten rock. “The removal of the north side of the mountain (13% of the cone 's volume) reduced Mount St. Helens ' height by about 1,280 feet (390 m) and left a crater 1 to 2 miles (2 to 3 km) wide and 2,100 feet (640 m) deep with its north end open in a huge breach (Wikipedia 3)”. The downwind of the eruption also destroyed many agricultural crops such as wheat, apples, potatoes, and alfalfa. Overall Mount St. Helens was a major blow that cost the US 1.1 billion dollars, and struck fear into the hearts of all of America on May 18th,
Yellowstone Park is the world’s first national park and the 8th largest national park in the United States. The park is primarily located in Wyoming and parts of Idaho and Nevada (56 Interesting Facts About . . . Var Addthis_config = ) It is a tourist attraction due it’s 5,000 to 15,000 years old geysers, over 45 waterfalls, canyons, rivers, hot springs, and its massive concentration of natural wildlife. Two of the most popular park attractions are the Old Faithful geyser and the Grand Prismatic springs. ("Fun Facts." - 32 Interesting Facts Yellowstone National Park.)
Mount St. Helens is an active stratovalcano in Skamania County, Washington, in the Pacific Northwest region of the United States. It is located 96 miles south of Seattle and 53 miles northeast of Portland, Oregon. The mountain is part of the Cascade Range. It is most famous for a catastrophic eruption on May 18, 1980. That eruption was the most deadly and economically destructive volcanic eruption in the history of the United States. 57 people were killed, and 200 homes, 47 bridges, 15 miles (24 km) of railways and 185 miles (300 km) of highway were destroyed. The eruption blew the top of the mountain off, reducing its summit from 9,677 feet to 8,364 feet in elevation and replacing it with a mile-wide horeshoeshaped crater.
The eruption on Mount Saint Helens has a specific cause and comes with many effects. A multifold of people would say that the “mountain looked like the site of an atomic blast” (Bredeson 30). That is a very accurate depiction as it took great power to inflict as much damage as it did. The reason for this impressive amount of force is that when magma is built up with pressure and an earthquake hits, the pressure gets magnified and the volcano explodes (Lewis). This is exactly what happened inside Mount Saint Helens. Furthermore, it has been revealed that “The earthquake that triggered the explosion was a 5.2 on the Richter scale” (Gunn 559). The earthquake to the magma can be compared as a match to gasoline. Even though the earthquake was not huge, the scale of the eruption was much greater than that of the earthquake (Gunn 560). The earthquake was only the trigger that allowed for more devastating things to occur. Thirteen hundred feet of the volcano were lost in the explosion followed by landslides, mudslides, and lava flows...
Deep within the Washington wilderness in the shadows of Mount St. Helen lies the infamous Ape Canyon. Upon these steep shallow cliffs, strange encounters have emerged over the past century. In 1924 a group of seasoned miners set out on a routine expedition searching for gold. However, what they encountered changed their lives forever. It was here that allegedly famous attack by a group of sasquatches occurred. In the short autobiography, I Fought the Apemen of Mt. St. Helens by Fred Beck, one of the miners, recollects his parties encounter with the beast.
The first time I saw Mt. Rainier for myself, was last summer when my boyfriend and I drove to Washington. It was the most beautiful, peaceful looking mountain I have ever seen. However, underneath it's great beauty, it hides a deadly secret. Mt. Rainier is one of the most dangerous volcanoes that we have here in the United States. One of the reasons it is so dangerous is because of it's great beauty. People enjoy looking at it, and the area that surrounds it, so they have made their homes here. Mt Rainier is not the only volcano I am interested in, in fact this last summer I also went to Mt. St. Helens and Crater Lake. But it is the volcano I chose to research for this paper because it does have so much beauty and at the same time so much power. I already know the basics about volcanoes, how they form, the different types, etc., but I wanted to find out more about what would happen if this great volcano were to erupt, what type of eruption would it be, and how would it affect the people that live around it.
Pompeii, rome was a city that had an extremely interesting and sublime history, this city had gone through a disaster that enabled many archeologists to find many artifacts that were held inside of this city of ash. In 79 AD Mount Vesuvius erupted, encasing the town in a sheet of not lava, but pure volcanic ash that caused for the city to have been completely buried and hidden from the world, Pompeii was no to be rediscovered for many years to come. "The ruined city remained frozen in time until it was discovered by a surveying engineer in 1748." (Owens). The eruption of Mount Vesuvius had caused for the city of Pompeii to remain in a "Time Capsul-like" state, making it a preserved ground for exploration.
Pompeii was a Roman city in Italy located 14 miles from Naples, and next to an active volcano named Mt. Vesuvius. In 79 A.D. the volcano erupted. The eruption had many stages. The first stage of the eruption was the tremors that happened the days before the eruption. The second stage of the eruption was a series of small eruptions from Mt. Vesuvius. The third stage was the very large eruption from Mt. Vesuvius. After the third stage the sun was clouded out with ash from the volcano. Lastly, the streets flooded with ash. The ash that flooded the streets perfectly preserved the city. When a surveying engineer discovered the city in 1748, the city was excavated from the ash and to the people's surprise, nearly everything was perfectly preserved, like a snapshot of history. Under the ash, the researchers found preserved remains of the people that lived there, bread still in ovens,
Pompeii was destroyed in 79 A. D. When the eruption of Mount Vesuvius started, 1.5 million tons of ash rock shot out Mount Vesuvius every second. After the eruption was over, Pompeii was buried in volcanic ash. Pompeii was just recovering from an earthquake in 62 A. D. The people in Pompeii were not ready for both events. Sixteen thousand people died when Mount Vesuvius’ eruption was over. (“Ancient Rome for Kids: The City of Pompeii;” Bagley).
The eruption and tsunami in the movie Pompeii was very different compared to the actual destruction of the city of Pompeii. In the movie Pompeii the eruption was shown as a very fast occurring event. The destruction of the city happened in less than a day and there was no fore warning of any of this previous to the day. In reality the destruction of Pompeii lasted about three days of continuous volcanic ash piling up on the city grounds. “The eruption of Mount Vesuvius buried Pompeii, Herculaneum and other surrounding cities in 13 to 20 feet (4 to 6 meters) of volcanic ash.” (Lewis, www.livescience.com) “Also, a Roman administrator, Pliny the Younger recorded that there had been several earth tremors in the days leading up to the eruption.” (www.ducksters.com) The movie also had huge lava bombs shooting out of the volcano and landing all around the city which was not closely related to anything that happened with the eruption. The real eruption of Pompeii consisted of clouds of dust and gas layering the city along with volcanic ash all at extremely hot temperatures. The destruction of Pompeii consisted of a tsunami as well but it was ve...
Vast areas of the USA would be destroyed, the US economy would most likely collapse, and thousands of people might die. If these super volcanoes do exist, they would have many other effects in the world. For example, once the part of Yellowstone erupts, if it were to rise up to 30, 40, 50 km we would instantly be distinct. Other super volcanoes would be killing ten thousands of people, plants would die and crops would have less time to grow as it would be colder. Magma would be spread at least 50 kilometres into the atmosphere.
while trying to help the residents of Pompeii. Today the type of eruption that Mount Vesuvius
In the city of Pompeii, people sat outside, enjoyed the sun and not have a worry in their minds. This came to an end, as the sky turned black, everyone had to run for their lives to escape the volcanic eruption. In 79 A.D., Mount Vesuvius erupted near Pompeii and buried this ancient Roman city, many people died before their time. Before anyone could understand why this is such a popular event in world history, it is best to know about the city of Pompeii and the events that followed after. If a student heard about Pompeii, it would have appeared to be another tragic event in history that led to a large amount of people dying.
Mount Vesuvius is a strato-volcano consisting of a volcanic cone (Gran Cono) that was built within a summit caldera (Mount Somma). The Somma-Vesuvius complex has formed over the last 25,000 years by means of a sequence of eruptions of variable explosiveness, ranging from the quiet lava outpourings that characterized much of the latest activity (for example from 1881 to 1899 and from 1926 to 1930) to the explosive Plinian eruptions, including the one that destroyed Pompeii and killed thousands of people in 79 A.D. At least seven Plinian eruptions have been identified in
